10 litres of 100% pure Methyl alcohol is added to a 5 litre solution containing 40% Methyl alcohol. What is the strength of Methyl alcohol in the resultant mixture?

A) 60%
B) 70%
C) 50%
D) 80%

Correct Answer:




D) 80%

Description for Correct answer:
The strength of Methyl alcohol in the resultant mixture is given by,
\( \Large C_{M}= \frac{C_{A}Q_{A}+C_{B}Q_{B}}{Q_{A}+Q_{B}}=\frac{ \left(10 \times 100\right)+ \left(5 \times 40\right) }{15}=\frac{1200}{15}=80\% \)
